Oscar Iso-Mount Type1

The easy to install, space saving, isolating acoustic hanger, ideal for soundproofing basement ceilings.  Loses only a few millimetres ceiling height but outperforms far deeper systems.  The installation can easily be carried out by a builder or competent DIY person.

Soundproofing a basement ceiling doesn’t mean you have to lose ceiling height because the Iso-Mount acoustic hangers are screwed to the side of timber joists instead of underneath.  This purpose designed basement ceiling soundproofing system ensures absolute minimum ceiling height loss.

Oscar Iso-Mount testimonials

"Ceiling is complete...

I've tested it by powering up a loud DeWalt router in the garage and seeing how loud it is in the room above.

WOW.  Can hardly hear it...It really was much quieter than I thought it would be.  I can finally use the workshop in the evening when the kids are asleep in the room above.  I'll admit not having done it before I was unsure if it would deaden the noise enough for power tools...but I am blown away by how well it works.

Thanks again for your help - much appreciated."

“The whole transaction has been simple and easy.  I fitted the ceiling this weekend and it’s made an instant difference.  So much so that I had to ask the owner of the flat above if he had been using the room above.  I will recommend the product to my friends and will use it on other ceilings in my flat. Keep up the good work!”

How much sound will an Oscar Iso-Mount soundproofing basement ceiling eliminate?

Acoustic testing has shown that a significant failure of Building Regulations Approved Document E can be turned into an easy pass. Independent testing on a house (ref 19 Wilberforce Road) showed that resistance to airbourne sound (speech, music etc.) increased by 23dB DnT, + Ctr and impact sound insulation increased by 24dB LnT,w; a significant and worthwhile difference.

The installation of the Oscar Iso-Mount Sound proofing ceiling easily complied with the stringent requirements of the 2010 Building Regulations Approved Document E for Airbourne and Impact Sound.

Why use a Oscar Iso-Mount soundproofing basement ceiling system?
  • Absolute minimum of ceiling height loss
  • Adjustable height enabling flat ceilings across uneven joists
  • All work is done from the flat below
  • No access is necessary to the room above
  • The installation of the acoustic ceiling is within the capability of a competent DIY person
  • The system has built in tolerance to allow for reasonable inaccuracy by the acoustic ceiling installer

How does sound transmit through floors and walls?

Sound passes through ceilings and floors as vibrations.  Sound pressure waves generated by footsteps, music or voices in an upper flat, penetrate and travel through the floor boards, joists and ceiling in the form of vibration.  They radiate from the ceiling as sound pressure again; weaker but in many cases still too powerful and loud.  Either side of joists, the sound pressure turns to vibration through the floor – back to sound pressure through the air void – vibration again through the ceiling – and back to sound pressure in the flat below.

How does it work?

Two factors are fundamental to the success of soundproofing a basement ceiling:

  • Break the path of vibration between ceiling and floor above with Oscar Iso-Mounts
  • Absorb the sound pressure passing through the void...

...with a high density acoustic absorber packed into the space without gaps: we recommend our acoustic absorber insulation for larger areas of 100m2 plus Celbar recycled loosefill cellulose fibre.  Celbar is a better insulator than glass fibre and doesn’t have the irritating itch.

Soundproofing of timber and concrete ceilings with our Oscar Iso-Mount Type2

The Iso-Mount Type2 significantly expands the versatility of our Oscar Iso-Mount range of isolating acoustic hangers for soundproofing ceilings.  The Iso-Mount Type2 can fix under existing ceilings without disruption, directly or with extensions for 50mm to over 1 metre voids for acoustic/thermal insulation and services.

Screw direct to concrete using just 1 concrete screw per hanger
into plasterboard using 1 screw fixing into the timber joist per hanger

Oscar Iso-Mount Type1

Acoustic hanger for timber joist ceilings

  • The minimum of ceiling height is lost: as little as 6mm (less than 1/4 inch)

Celbar - recycled insulation

Celbar sound insulation

Celbar is recycled environmentally friendly acoustic and thermal cavity/void fill sound insulation made from paper based materials treated for fire retardancy.  Tests have shown that when packed together, this natural, recycled cellulose insulation material is acoustically and thermally more effective than man-made mineral wool.
